Percona XtraBackup 2.2.8

Percona is glad to announce the release of Percona XtraBackup 2.2.8 on January 14th 2015. Downloads are available from our download site here and from apt and yum repositories.

This release is the current stable release in the 2.2 series.

New Features

Percona XtraBackup has been rebased on MySQL 5.6.22.

Bugs Fixed

Incremental backups would fail if the number of undo tablespaces (innodb_undo_tablespaces) was more than 1. This was caused by innobackupex removing the undo tablespaces during the prepare phase. Bug fixed #1363234.

Fixed multiple memory leaks detected by AddressSanitizer. Bug fixed #1395143.

innobackupex could fail when preparing backup that was taken from Percona Server 5.5 with log files (log_file_size) bigger than 4G. The root cause was that the last checkpoint LSN offset in log group is stored at different offsets in ibdata1 for Percona Server 5.5 and MySQL 5.6 when the total size of log files is greater than 4G. Bug fixed #1403237.

Percona XtraBackup out-of-source builds failed. Bug fixed #1402450.

All of Percona’s software is open-source and free, all the details of the release can be found in the 2.2.8 milestone at Launchpad. Bugs can be reported on the launchpad bug tracker.
